Fixed pt-br typos

[ewertones]

• The first "Java" is missing from the first quoteblock;
• The word "ocioso" is spelled wrong ("oscioso");
• Also I've replaced two commas with colons because we use that before citations.

@ewertones Why did you close this before? Anything to adjust in your PR?

@rffontenelle I deleted the forked repository by mistake, so Github closed the PR automatically.
